For example, among the cables ASSY 109 connected to the power connector 8, a cable (power line 14) that supplies a voltage is connected to the switch 13. When the power supply substrate fixing plate 101 is pulled out and the switch 13 is pressed by the step portion 112, the power supply is cut off (cut off).

The switch 13 is a switch that does not return after being pressed and returns to the non-pressed state, such as a push-lock switch.
Examples of such a switch include a switch that performs a turn reset operation and a switch that performs an alternate operation. The switch that performs the turn reset operation is one in which the ON state of the contact is held (locked) by an internal mechanical lock mechanism when the button is pressed, and the lock is released when a twisting operation is performed. Examples of the switch that performs an alternate operation include a push-push switch and a push-pull switch. The push-push switch is a switch in which the ON state of the contact is held (locked) by the first pressing operation, the lock is released by the second pressing operation, and the contact returns to the OFF state. The push-pull switch is a switch that holds (locks) the ON state of the contact by a push operation, and releases the lock and returns the contact to an OFF state by pulling back the switch.
As another switch, a holding-type limit switch can be provided. In this case, a projection is provided in the middle of the movement of the power supply substrate fixing plate 101 or the power supply substrate 6 being pulled out, and the switch is turned on when the projection passes.

In a camera apparatus having an interface board for holding and connecting an external cable and an internal connection cable and a fixing base having a fixing board for fixing the interface board, the fixing plate can be pulled out of the fixing base. A switch that has a stopper function that prevents the interface board from being pulled out beyond a predetermined length when the interface board is pulled out to a predetermined length, and cuts off the power connected to the interface board from an external cable. And the problem of the present invention is solved.

The switch 13 may be attached at any position as long as the protrusion 111 is in contact with the step 112. Moreover, you may attach to the level | step-difference part 112 side instead of the projection part 111 side. Further, the protrusion and the switch may be attached separately, or a plurality of protrusions and switches may be provided.
In addition, a sensor such as an infrared sensor is provided, and for a component that can be identified as moved, such as the connector of the power supply substrate fixed plate 101 or the connector ASSY10, the power is turned off when the sensor is identified as moved. You can leave it.
